Watch: Teaser for 'Game of Thrones' Season Three, Set to The National

There's no footage from the upcoming season of "Game of Thrones" in HBO's latest teaser for the series, but it does present a glimpse of the three-eyed raven that appears in Bran Stark's (Isaac Hempstead Wright) dreams traveling through familiar and decidedly non-Westeros territory. The song playing is "The Rains of Castamere," which in the book was written about Lord Tywin Lannister's (Charles Dance) victory over and destruction of the rebellious House Reyne of Castamere. This version is performed by the National and played over the closing credits of the season two episode "Blackwater," directed by Neil Marshall ("The Descent").
